Title: Unit injector
Inventor: HORIUCHI YASUHIRO
IPC: F02M51/00
Filed: 1989-08-07
Abstract: PURPOSE:To preclude generation of the smoking phenomenon and prevent counterflow of combustion gas into a nozzle by applying the overflowed pressure oil to a nozzle spring chamber when a control valve is opened at the finishing time of injection,and allowing the nozzle to close valve quickly. CONSTITUTION:If the voltage of a piezo laminate 19 is sunk when the injection end timing is attained, a spill valve element 61 moves to the right. At this moment, part of the high pressure fed fuel passes through a valve seat chamber 64 and a back pressure port 66 and flows into a nozzle spring chamber 5 vigor ously. This raises the pressure in the nozzle spring chamber 5, which acts on a needle valve element 11 to depress it. Thus the needle valve element 11 shuts certainly and quickly, and injection of the fuel is finished. Further, the back pressure port 66 leading from the valve seat chamber 64 to the end face of the needle valve element 11 is short, and the valve seat chamber 64 and back pressure port 66 are positioned alongside the stream of the fuel, so that the pressure in the nozzle spring chamber 5 rises in the style with the dynamic pressure portion added, which enhance the effect still more.

Abstract: PURPOSE:To provide a syringe containing a couple of medical fluids which are prohibited to be in a ready-mixed state prior to injection, wherein the longitudinal length of a reservor room located at the end of syringe is designed to be longer than the sum of the longitudinal length of two stop-rings. CONSTITUTION:Sealing effect for a medical fluid 22 by the first stopper 9 is lost when a stopper 9 is plunged completely into a reservor room 14 by pushing a plunger rod 7, because a fluid 22 is compelled to flow by a forward movement of the second stopper 11 through a groove 18 into a needle 3 via a reservor room 14. Thus, almost all of a fluid 22 is delivered out when the two stoppers (9 and 11) come into contact with each other. As the longitudinal length L1 of a reservor room 14 is larger than the sum of the longitudinal length (L2 plus L3) of two stoppers (9 and 11), a medical fluid 23 is compelled to be delivered out of a syringe through the same path as a fluid 22, by a forward movement of a rod 10.
